This experiment was performed to compare how adding fruit paste to bread made it last longer without s. The tests were done using paste made from prunes, raisins and dates added to the bread before baking.

Fungi often go unseen because of their small size, but they are important to us in many ways. Some fungi are beneficial to us and are used to make medicine, such as penicillin. Yeast, a kind of fungi, causes bread to rise in baking. Other types of fungi are not so beneficial, and can cause diseases such as athlete's foot and other infections. Fungi need particular conditions for growth

I wanted to develop a hands-on activity related to my field of interest -- civil engineering with an emphasis in pavement and materials. Asphalt cookies were the perfect solution. Asphalt cookies are chocolate no-bake cookies. The process of making these cookies parallels the procedures used to produce asphalt pavements.

Spaghetti is denser than water and, therefore, sinks when placed in water. When spaghetti is placed in a solution of baking soda and vinegar, the spaghetti rises to the surface due to the carbon dioxide gas that adheres to it. When the spaghetti reaches the surface, the gas is released, and the spaghetti sinks again.

The yeasts are one very important group of fungi. The common yeast used in baking bread grows very fast. You can complete an experiment in two days! The basic idea in this method is to measure the amount of carbon dioxide (CO2) released during the growth of yeast.
